I would first look underneath where the cables connect on the right side of the trans. Maybe have a friend try and shift it while you're under there. Look for anything that might look out of place. If you don't find anything out of the norm there. I would say take your shifter boot off and look down in the shifter for any jamming. If you still can't see any problems, you may have to take your center console out so you can get an even better look at your shifter. Anything more than that and you might have some trans issues.
